Rate of a reaction is dependent on:

Explanation

OPTION A: The rate of reaction is dependent more on the concentration of reactants. The concentration of reactants directly affects the number of collisions between them, which determines the rate of reaction. Increasing the concentration of reactants increases the number of collisions and thus the rate of reaction.OPTION B: The rate of reaction is independent of product concentration because it is determined by the concentration of reactants and the rate-determining step.OPTION C: The rate of reaction is also dependent on the slowest step in the reaction mechanism. However, if the concentration of reactants is increased, the rate of reaction can increase even if the slowest step remains the same. So, the rate of reaction is more dependent on the concentration of reactants than the slowest step.OPTION D: This option is incorrect.
